자주 묻는 질문:
  • What standards does this testing machine comply with?
    The machine is designed and manufactured in accordance with the GB/T9251-2021 'Test Method for Hydraulic Pressure of Gas Cylinders' standard.
  • How does the machine measure the volumetric residual deformation rate?
    It measures deformation by placing the cylinder in a water jacket; when pressurized, cylinder expansion displaces water into a measuring cup, and the remaining water after depressurization indicates residual deformation, which is calculated as a ratio to total deformation.
  • What types of gas cylinders can this machine test?
    It is applicable for regular inspection of compressed natural gas cylinders and cylinders of various types and specifications.
  • Is the testing process automated?
    Yes, the entire testing process, including weighing, water filling, and hydrostatic testing, is controlled by an industrial control computer for accuracy and efficiency.
